Surveys are often associated with analytics. Almost all surveys are heavily weighted towards collecting, what market researcher's call, closed-ended data. Open-Ended text data (aka freeform text), however, is different in the sense that there is no concrete question.
Users are asked to give their opinions on a subject via free-form text. Open-ended comments on surveys cannot be consolidated and analyzed easily. They are a boon because it allows your respondents to "open up" and give you comments, ideas, and suggestions that you were not even asking them.
QuestionPro text analytics focuses on ways and techniques you can use to extract the value out of the open-ended comments that your respondents leave.
